some people like peptides some do not. but the growth secretogs (spelling?)(ghrp's,CJC's,Ipam) seem to work on serum growth secretion. I am not a big growth guy and gh is so cheap now its not much cheaper to go that route any more. HGH frag can promote weight loss. I have used it before but its not miracle drug. I was eating at a deficit and doing cardio. Melatonin 2 will get you beach ready tan.
Those are the only ones I have used over the years.
